To @ZZ whom t may concern.'

Be it known that I, FREDRIC C. IVEIR, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a certain new and usefulImprovement in Spring-Frogs, of which the following is a specification.

My invention relates to a sl'iring-frog.

The object of my improvement is to produce amore durable andcasier-operating device, all of which will be fully set forth in thedescription of the accompanying` drawings, making a part of thisspecification, in whichi Figure 1 is a top plan view ment. Fig. 2 is asection on line .fc se, Fig'. l. Fig. 3 is a section on line y y, Fig.l. Fig. 4E is a modification of the method of connecting the spring-railto the frog-plate. Fig. is a top plan view of a section broken off toshow the construction. Fig. 6 is a section on line .e 5, Fig. 5. Fig. 7is a top plan view of a modification. Fig. S is a central section online if o, Fig. 7. Fig. .f-l is a top plan view of anothermodifii'fation. Fig. l() is a side elevation of Fig. 9.

l represents a base-plate, en which the frog rests.

2 3 represent the point-rails.

-lrepresents the stationary rail, and 5 the movable spring-rail.

6 represents the iilling lmlween the and stationary or wing rail.

7 lreln'esents through-bolts passing through the point-rail andstationary wing-rail and through filling-block G, so as to form a rigidconstruction.

8 represents a fish-plate attached to the depending arm i), which passesdown through the slot lO.

ll represents a friction-roller attached to the under side ot' the armfr), adapted to roll. against the underside of the plate, and serv-- ingthe function ot' holding the spring-rail down.

l2 represents a friction-roller on the top of the plate. In Fig. 5 isshown a slot, 14, for insertion of the T et' arm 9, so as to place it inposition. l5 represents a spring to bring the springy rail 5 back intoposition when it has been opened for the passage of a train. In Fig. 7 Ii have shown a narrow base-plate, simply large t' of my im provepointenough for the slot l0 and the frictional support of the arm 9 on theunder side. It is slotted through at one end to permit the T of the arm9 to be inserted into slot 10, and the slot is then closed by plate 18.

1G represents a fish-plate attached tothe web of the fixed wing-rail andsecured to the base-plate.

17 represents a vfilling-block. In the modifications shown in Figs. 7and S the base-plate l is bent up to form a fish-plate support, 1G, asshown in Fig. 8. By means of the arm 9, rigidly attached to thespring-rail and turning down through the slot in the base-plate, andwith the lug` bearing on the other side of said plate, the spring-railis held against vertical displacement. A friction-roller may be used insaid lug. The spring-rail, supported as herein shown, is easily moved onits base in the operation of switching a train.

In Figs. 9 and 10 another modification shown. a l) represent slots, andarm 9 is 'forked and projected down through each of said slots. A yoke,c, engages over the forks of said arm 9, which are preferablyscrewthreaded to receive nuts d to hold said yoke in place and providethe bearing or holdingdown support of the spring-rail.

It will be observed in Fig. l, by the dotted lines e, that the plate S,to which the arm 9 is attached, extends a considerable distance forwardof the arm. 9. This is for the purpose o1. not only strengthening therail against breakage, but it performs another very important Office inease of accidental breakage ofthe rail, as it holds the two sectionstogether and prevents dera-ilment of the train passing over it.

Having described my invention, what I claim is* 1 l. In combination withthe spring-rail 5, the arm 9, bent and projected through the slot in thebase-pl ate, having' a movable bearing upon the under side of saidplate, substantially as specified.

9. lIn combination with the spring-rail 5, resting on the base-plate l,the arm 9, attached to said rail and bent through the slot in saidbase-plate, and provided with one or more frictionrollers bearingagainst said plate, substai'itially as herein specified.

A spring-frog composed substantially of the point-rail, 'the base-platel, and fish-plate IOO 16, secured together 'by through-bolts having'Sprmgd'ail, 5, moving on said basefplme and plovlded with :L 'frctinnzdhealing-support,

substantially as hol-ein specified.

In testimony whereof I have hereunto set 1o my hand.
